We have a long-used Tbird system on a PC. One of the files in the profile (/ImapMail/../Inbox is > 4GB.

We need to migrate to a MacOS 12.16 machine. I've already copied all of the smaller files in our Tbird profile over. I can't copy the >4GB file to a Fat32 drive because it exceeds Fat32 file sizes. Any hints on how to do this? What is the format of an Inbox file - it looks like it might be some kind of archive?

I suggest using the importexport addon to export the 4gig folder to eml files and then import them after the move.
